About this study
Official title: A Clinical Study to Evaluate the Safety, Efficacy and Pharmacokinetics of Recombinant Von Willebrand Factor (rVWF) With or Without ADVATE in the Treatment of Bleeding Episodes in Chinese Subjects Diagnosed With Von Willebrand Disease
The main aim of this study is to find out if VONVENDI is safe for adult Chinese participants with VWD. The study will also check how well VONVENDI helps control bleeding with or without product ADVATE in the participants who may need elective surgery or dental procedures. In addition, the study will also examine how VONVENDI is processed by the body (known as pharmacokinetic [PK]) and how the drug helps the body respond or improve a condition (pharmacodynamic [PD]).
Participants will receive an initial dose of VONVENDI of 40 to 80 international units per kilogram (IU/kg) of body weight. If a participant's baseline factor VIII (FVIII) level is not high enough to help stop bleeding, VONVENDI will be given along with 30 to 45 IU/kg of ADVATE rFVIII.
Participants will be in the study for approximately 14 months. During the study, participants will be followed up at clinics or over telephone calls.

Measured: At 24 hours or Day 14
Total Volume of Actual and Predicted Intraoperative Blood Loss After the Surgery as Assessed by the Operating Surgeon
Intraoperative actual blood loss will be assessed by the operating surgeon at the completion of surgery using a predefined 4-point rating scale. 1- Excellent (intraoperative blood loss was less than or equal to the maximum expected for the type of procedure performed in a hemostatically normal individual [<=]100 percent [%]); 2- Good (intraoperative blood loss up to 50% more than the maximum expected blood loss for the type of procedure performed in a hemostatically normal individual [101%-150%]); 3- Moderate (intraoperative blood loss exceeding 50% of the expected for the type of procedure performed in a hemostatically normal individual [greater than (>)150%]); 4- None (uncontrolled hemorrhage due to an inadequate therapeutic response despite appropriate dosing, necessitating a change of clotting factor replacement regimen). Lower scores indicate better hemostatic efficacy. Scoring is calculated by comparing the actual blood loss versus predicted blood loss.
Measured: From Intraoperative through completion of surgery (up to Day 14)
Intraoperative Hemostatic Efficacy Score as Assessed by Operating Surgeon at Completion of Surgery
The hemostasis assessment rating scale ranges from 1 to 4, where 1 = Excellent, 2 = Good, 3 = Moderate, and 4 = None. Lower scores indicate better hemostatic efficacy.

Daily intra- and postoperative weight-adjusted dose of VONVENDI with or without ADVATE through postoperative day 14 will be reported.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The main aim of this study is to find out if VONVENDI is safe for adult Chinese participants with VWD. The study will also check how well VONVENDI helps control bleeding with or without product ADVATE in the participants who may need elective surgery or dental procedures. In addition, the study will also examine how VONVENDI is processed by the body (known as pharmacokinetic [PK]) and how the drug helps the body respond or improve a condition (pharmacodynamic [PD]).
Participants will receive an initial dose of VONVENDI of 40 to 80 international units per kilogram (IU/kg) of body weight. If a participant's baseline factor VIII (FVIII) level is not high enough to help stop bleeding, VONVENDI will be given along with 30 to 45 IU/kg of ADVATE rFVIII.
Participants will be in the study for approximately 14 months. During the study, participants will be followed up at clinics or over telephone calls.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing VONVENDI and ADVATE in people with Von Willebrand Disease (VWD), run by Takeda at 7 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Takeda Contact (+1-877-825-3327, medinfoUS@takeda.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) (time frame: Up to 14 months). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jan 2026.
